It demonstrates a software application that resizes images in such a way that the content of the image is preserved intelligently. The video describes it better than I can, but the basic idea is that if you want to stretch out an image, it will keep the key elements of the photo in sensible places while filling in less important areas. The same goes for shrinking an image - it will eliminate the less important features of an image and leave the main subject areas intact and in the same relative location as they previously appeared in the image.Dr. Ariel Shamir and Shai Avidan wrote about this technology in ACM Transactions on Graphics, Volume 26, Number 3, SIGGRAPH 2007.
Watch the video then think about how this could be used to deliver images to your users. Then think about how it could be used to alter reality (as if we couldn't do so already). Then say "wow"!
